Jesse Eisenberg showed off his sleight of hand Tuesday at a party for his new film about magicians who are bank robbers, “Now You See Me.” We’re told the Hudson Hotel on West 58th Street was decorated with scattered playing cards. “Jesse picked them up and was doing tricks for an audience,” a witness reports. The actor wasn’t the only pro in the house — David Copperfield, mentalist Keith Barry and illusionist David Kwong were also in attendance. Staying on theme, we’re told fake money fell from the second floor into a crowd including Woody Harrelson, Isla Fisher and Michael Caine, who spies said had his reserved table moved to be close to Morgan Freeman.
